You can use the formula P1V1= P2V2

(1.90)(6.32L)=P1(3.49 L).

Solve for the unknown.

P1= 3.44 atm

Las Vegas, Nevada is in a desert. How does its rapid population growth affect the
Scrat [10]

Answer:

Many areas of the United States experience explosive population growth. <u>The more people that reside someplace, the more demand there is for water there.</u> Often these urban-growth <u>expansions are unplanned and place extraordinary stress on the water supply system, mainly on the groundwater.</u> <u>The stress often depletes groundwater supply, thereby causing wells to dry up.</u> Then water must be brought from somewhere else to support the local population.

Such situations have occurred all over the United States. For example, increased population growth in the southwestern United States has significantly lowered the water table 50 to 200 feet (depending on the area) since the 1940s. Managing urban growth, efforts to reduce water demand, conservation of the resource, and attempts to increase the water supply all address the problem of exceeding water resource limits.

<u>Human activities affect groundwater quality.</u>

<u>Here are some sources </u>and possible solutions to groundwater pollution:

<u>Agriculture</u>—Reduce usage of pesticides and fertilizers.

<u>Landfills</u>—Monitor for leakage and repair linings.

<u>Underground storage tanks</u>—Remove damaged and unused tanks.

<u>Household wastes</u>—Properly dispose of household hazardous waste.

<u>Septic tank leaks</u>—Properly maintain and repair tanks.

olchik [2.2K]

Answer:

During photosynthesis SOLAR enerrgy is transformed into CHEMICAL energy.

Explanation:

In nutrition, green plants manufactures their own food which they use for both energy and growth. This is called an autotrophic mode of nutrition.

Therefore, photosynthesis is an autotrophic nutrition in which plant can build sugar by taking carbon dioxide from air and water from the soil. For the synthesis of sugar like glucose, carbon dioxide provides carbon

and oxygen whereas water molecules provide hydrogen. The plant builds sugar molecules from these simple compounds. Enzymes needed for this purpose are present in the cells and energy is trapped by chlorophyll from sunlight. This process is summarised in the equation below:

Sunlight (solar)

6CO2 + 6H2O--------------------> C6H12O6 + 6O2

From the equation, Carbon dioxide, water and sunlight (SOLAR energy) is the raw materials needed to produce Glucose and oxygen (CHEMICAL energy) as by products.

Determine the hybrid orbital of this molecule.
Pavel [41]

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.

<h3>What is hybridisation?</h3>

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

In this compound, sp^3 a hybrid orbital makes I-O bonds. Due to sp^3hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of IO^{3-} the ion is pyramidal.

The hybrid orbital of this molecule is sp^3. Hence, option C is correct.
